- Lucretia model server conversion
- python PVA service
- matlab interface class
- GUI conversion
| Global | Cesar, Perez, Buschmann | WIP | 1 | - 1/12/24: demo PVA server works, writing live/design Rs and twiss params, but matlab pvaGet not working yet. next step: document lucretia dependencies across matlabTNG to determine what the matlab interface needs to do
- 1/23/24: matlab PVA access works with a python workaround (good enough for now, likely need a better long-term solution) Cesar prepped draft interface design document. reviewed high-priority GUI model uses.
- 2/8/24: PVA server is running but not deployed to prod yet. Drafting implementation of matlab class F2_ModelReceiver - once the lucretia functions GetRmats, RmatAtoB and GetTwiss are replicated we can proceed to test GUIs. Need to check w/ controls deputes to get some watcher PVs set up
- 3/12/24: draft version of receiver on GitHub, testing for correctness and use by GUI controllers
- 4/9/24: F2_ModelReceiver 0.1 version is ready for deployment, unfortunately the python models service has some errors in it, but the mechanics of the interface are mostly stable
- 4/18/24: live model is currently starting from the gun, which produces very unrealistic twiss parameters. Need to start sim downstream at some treaty point – likely L0AFBEG or possibly L0BFBEG
- live model GUI gets marginally more realistic outputs starting from L0BFBEG, one option...
- more realistic: take the latest PR10571 emittance measurement, back propagate to initial twiss at L0AFBEG – there are some kind of hooks in place for this already. but I'm not 100% on if they ever worked...

- LEM server + watcher conversion
| LEM | Buschmann |
| 2 | Waiting on model server deployment
- 3/13/24: current plan is to deploy a second PVA server that writes LEM EREF/EACT/BDES etc to an NTTTable, then the ModelReceiver can be updated in-kind to provide those quantities
- python PVA will make it straightforward to build a LEM CUD

| Phase Scans | Buschmann | WIP | 2 | rudimentary functionality, needs with-beam test | https://github.com/slaclab/facet-matlabTNG/pull/4 |
- Add quad scan emittance measurement function (for L0)
| Optics Matching | Perez |
| 3 | last step needed to migrate off of the LCLS-side emittance application. seems to be already partially implemented, so the challenge here is partially archeological in nature. |
